What’s your Diagnosis?

In this feature, AAOS Now publishes a series of images, challenging readers to diagnose the condition depicted. The images for this month’s challenge were submitted by Meagan McCarthy, a fourth-year medical student at Creighton University School of Medicine, who plans to pursue an orthopaedic surgery residency. She provides the following information:

“The patient is a 66-year-old recent Burmese immigrant with a 6-year history of soft-tissue masses of his left hand and both feet. At the time he was examined, the masses were neither painful nor tender to palpation. Radiographs of both feet and left hand are shown.”
